My supervisor replies slowly and is hard to reach
Make your requests easy to answer, follow up without awkwardness, and know when slowness becomes a problem to raise.
In short
Start here, today. Open the Waiting-For List and add everything you're currently waiting on from your supervisor, with the date you asked. Give each item a follow-up date. This takes about 15 minutes.
After that, work through these steps. Choose one to jump to it.

Make each email easy to answer
Put the request in the subject line, such as “Decision needed: interview sample size, by 14 March”. Ask one main question per email, near the top, and offer options rather than an open question. A supervisor can reply “option B is fine” from their phone between meetings.
Give a date and a reason
“Whenever you have time” often means never. Say when you need it and why: “I'd like to submit the ethics application on 3 May, so comments by 26 April would give me time to revise.” If a whole chapter is too much, ask for comments on the two sections you're least sure of.
Track what you're waiting on
Log every request in the Waiting-For List the day you send it. If you don't know how long to wait, use the turnaround you agreed in your expectations conversation, or two weeks. When the date arrives, follow up, even if it still feels awkward.
Follow up politely and specifically
A follow-up is not nagging. Keep it short, restate the one thing you need, and attach the document again so they don't have to search for it. If email isn't working, ask whether a ten-minute call, or a few minutes after a seminar, would be easier for them.
Use the rest of your committee
Co-supervisors, committee members and postdocs in your group can often answer a methods or literature question faster. Keep your supervisor informed rather than going around them: mention who you asked and what you learned. This also builds the relationships you'll need at your defence.
Know when to raise it
If you've had no substantive feedback for several months, if delays put a program deadline or your funding at risk, or if your supervisor is away for a long period with no cover arranged, speak to your graduate coordinator. Bring dates and facts, not frustration. Some programs set expectations for supervisor availability and turnaround times, so ask whether yours does.
Words you can use
Is this you? Signs to look for
- You've been waiting weeks for comments on a draft and don't know whether you can ask again.
- Your emails get answered eventually, but often only the last line.
- You plan your week around a reply that doesn't come.
- Asking a second time has started to feel rude, so you wait.
- Meetings get moved or cancelled almost as often as they happen.
Why this happens
Slow replies are rarely personal. Many supervisors carry several doctoral students, teaching, grant deadlines and administrative roles alongside their own research, and an email from a student often loses to whatever is loudest that day. A long, open-ended message is especially easy to postpone, because answering it properly needs a block of time they don't have.
That doesn't make the delay harmless. Your timeline depends on their input, and a month of silence can stall a chapter or push back a milestone. The part you can change is how your requests arrive. Short, specific requests with a clear question and a date get answered faster by almost everyone.
There is also a point where slowness stops being a habit and becomes a problem. If you go months without meaningful feedback, or a formal deadline is at risk, it is reasonable to involve someone else.
When to bring someone in
Go to your graduate coordinator if slow responses are affecting milestones, funding or program deadlines. They can often speak to the supervisor informally, and if your supervisor is on leave or sabbatical, they should make sure you have interim supervision. If nothing improves, the program director or an ombudsperson can advise you on your options, including adding a co-supervisor.
